Missing AP Wifi Mode on latest update
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hi,
I recently updated my OC200 to latest firmware, I noticed that I am unable to select wifi mode for the APs (I have 4 EAP245-v3, latest FW).
On previous firmware I was able to select 802.11 mode for each AP, since I want 802.11n mode only for 2.4GHz band
Before (Mode tab):
After (No mode tab):

@Fae, thanks for the clarification! A FAQ will be very helpful, thanks too for this!

Sorry, it's still confusing. Maybe it's me but would be easier to disable A, B, G and N with checkboxes or something like it, at least from the usability perspective.
Anyway, if I move the scroll all the way up to the 54mpbs for both 2.4 and 5 Ghz, does it mean that A/B and G are disabled ? Only N and AC clients are going to be allowed ?
Thanks

There is already a checkbox to disable b mode (»Disable CCK rates«).
In the past, lots of users requested to be able to restrict WiFi rates in Omada Controller as is possible in the Auranet AC500 controller. Now that we got it, this rate selection should be kept in SDN Controller.

For b/g: yes. But you should not do this if you have 802.11b/g networks around in your neighborhood, since disabling 802.11b/g completely turns of compatibility settings which are needed by your AP to operate properly with everyone else's APs. If you just disable 802.11b/g WiFi rates and the AP still uses the compatibility settings, this is not an issue. But if you turn off 802.11b/g and compatibility settings (as is done with checkboxes usually), performance degradation can happen even if you don't have 802.11b/g clients in your wireless network.
Much more useful is to be able to change the beacon rate, e.g. by increasing it to 11 Mbps, which saves AirTime. For example, at a (standard) beacon rate of 1 Mbps the AP needs ~2,5% AirTime. 10 APs (or 10 SSIDs) need 25% AirTime. Using a beacon rate of 11 Mbps all 10 APs require only 2,5% AirTime in total, thus increasing AirTime left for data transmissions.
That's why it is pretty much very useful to be able to restrict only WiFi rates w/o turning b/g modes off as can be done in SDN Controller.
If your network is the only one around, then disabling older modes can improve things a little bit (but not much).
Leaving 802.11a mode enabled does not degrade performance if you don't have 802.11a devices connecting to it. If you have such devices, it should be left enabled anyway. As for rate settings the same as described above for 2.4 GHz applies to 5 GHz.

@AndreMartins, yes, you could do so if you have no 802.11a clients, but 802.11n/ac only.

@Fae is there's a chance to customized only specific EAP225 Outdoor from OMADA devices instead in the controller. For I have total 16 EAP225 Outdoor deployed and different households having a diff scenario which I plan to customized the data rates as needed in specific areas.
Please advise.
Thank You.

Dear @LaboDJ,
I recently updated my OC200 to latest firmware, I noticed that I am unable to select wifi mode for the APs (I have 4 EAP245-v3, latest FW).

The latest firmware is updated to the SDN controller, which removes the support of changing 802.11 mixed mode for each AP.
May I know your actual purpose of changing the wifi mode?
If you have a higher-density network, you want to improve the network performance by disabling lower bit rates and only allowing the higher, it's suggested to configure 802.11 Rate Control under Settings > Wireless Networks, select 2.4 GHz and/or 5GHz band to enable minimum data rate control according to your needs, move the slider to determine what bit rates your wireless network allows.

Dear @JhonneL,

You can use WLAN Group function to customize the wireless setting for specific EAP. Refer to the following FAQ.
How to configure the WLAN Group function on the Software Controller (or OC200)
Note: the pictures in the FAQ above may not fully suit Omada SDN but the steps are similar.

I came looking for the same information....

Because objectively setting the mode works, and it's easy to see that it works. The rate control is woolly and inconclusive. Behind the scenes clearly the connection standards must be being applied, but it's opaque. Setting the sliders all the way to the right, does that result in 802.11ac only? Why not have the UI say that. Otherwise it makes testing client devices vague and subjective.
I have one client device when taken to a premises running old Omada contoller, connects at over 900Mbps. On my premises running OC200 4.2.8, it can barely get above 300Mbps. All other settings and scenarios have been changed to the same, the one final thing is to lock the wifi mode for testing.

There are also other important settings missing in the newest controller like FastRoaming, forced FastRoaming and BandSteering,
I am specifically interested in how Fast Roaming and forced Fast Roaming (older devices that do not support 802.11k) are working with the latest controller? What's the teoretical and practical switching client time from one AP to another and the SNR difference between APs to force client to change from one to another?
Also what's the SNR limit to steer client from 2,4GHz to 5 GHz band and vice versa to reduce down to 2,4GHz when 5GHz signal is not strong enough anymore?
